Sejong the Great (세종대왕)

"나랏말ᄊᆞ미 듕귁에 달아 문ᄍᆞ와로 서르 ᄉᆞᄆᆞᆺ디 아니ᄒᆞᆯᄊᆡ..." / "The sounds of our language differ from those of Chinese..."

"어리석은 백성이 말하고자 하는 바가 있어도 마침내 그 뜻을 펴지 못하는 자가 많으니라." / "Many common people have something to say but cannot express their meaning."

"A wise man can learn them before morning is over; even a stupid man can learn them in ten days."
